Interrupted backfill can leave stored observations separated by
missing trading time. Query dated IB sessions before prepending
stored history and reserve synthetic samples only during covered
open sessions. Keep venue closures compressed and preserve the
indexes of already published rows.
Deats,
- Add `Client.history_schedule()` with UTC coverage, extended hours,
bounded duration, timeout, and rejection of ambiguous DST times.
- Keep schedule normalization in `venues` and allocation in
`.tsp._reserve`, with the project AGPL headers.
- Expose schedule and synthetic-range queries through `datad.ib`.
- Bound reservations by available SHM capacity and inspect only the
newest 32 gaps by default via `newest_gaps`. Zero disables
queries; leave unknown and oversized ranges unresolved.
- Record synthetic ranges separately from OHLCV. Automatic storage
writes retain provider observations; placeholders copy close.
- Group the new tests under `tests/providers`.
- Cover request formatting, DST, failure and capacity cases, plus
real SHM/NativeDB startup placement with a fake provider.
- Document a common CLI/chart segment-repair interface and defer
coordinated insertion, repair execution, and reader integration.
Validation: 55 targeted tests passed in the working tree; live IB
schedule coverage remains unqualified. After the module moves,
33 affected tests passed again; the local review follow-up passed
18 affected cases, including four new request-budget cases.
The commit runner repeats
lint and isolated regression checks against this exact boundary.

Extract `_copy_close_to_null_rows()` with explicit mutation
bounds, searchable close-copy comments, and preserved activity
fields. Type and document `maybe_fill_null_segments()` including
its distinction from packed timestamp-gap repair.
Disable relative epoch tolerance when validating synthetic
stamps: an overfull reservation must not duplicate the right
boundary. Cover modern epochs, typed empty replies, packed gaps,
and unchanged rejected inputs.

Complete HMDS no-data replies without silently retrying a day
older. Let `open_history_client()` classify the original request
and leave frame stepping to `start_backfill()`.
Distinguish `request_end_dt` from `oldest_shm_dt` so the first
frame after an empty interval retains its unwritten end bar.
Inline the storage time cutoff and drop the unused two-direction
`diff_history()` helper. Explain both dates and filtering rules.
Add request-boundary tests and real SHM/NativeDB regressions:
all 2,004 supplied bars survive, while the closure stays empty.

Export `FeedQuote` and `Tick`, describe historical and realtime
FSP yields, and preserve callable parameters through `@fsp`.
Align builtin history arrays and emit named realtime updates.
Keep the staged Tuicr review fixes. Let Numba specialize `ema()`
lazily so omitted defaults work alongside explicit arguments,
retaining nopython/nogil compilation and single-sample seeding.
Cover builtin yields and EMA argument forms with regressions.
